I have a question regaridng watchdog reset.
1- Is it software or hardware reset ?
2- If reset pin is switched to low then high again , Does that mean that it is for sure hard reset ?
3- is there a register to reflect reset reasons ?
4- What is the effect of Invalid instruction on this target , jump to ISR and do WDOG reset if enabled or what is the behavior exactly please ?
Thank you in advance.
